Re: Shared memory in extensions

Alexander! You're absolutely right - that was exactly what I had done! Hmm I guess that at his point I have noone fooled :) I'm totally new to all this shm stuff and PHP extensions or rather the intrinsic details of their 'inner' workings... I simply figured that if I allocate a shared memory segment in PHP_MINIT_FINCTION then it should be destroyed in PHP_MSHUTDOWN_FUNCTION. The error I did (I reckon) was to compile and replace the PHP-module before restarting apache. This way the new PHP_MSHUTDOWN_FUNCTION was called before PHP_MINIT_FUNCTION. Where can I find a good explanation as to what the differences are between MINIT, RINIT, MSHUTDOWN and RSHUTDOWN? hehe - how would one go about removing a shared memory segment manually?? Well thank you all (Alexander in particular) for your answers they helped alot Thomas Alexander Feldman wrote: > > Hi Thomas, > > I tried to create a shared segment of size 5 megabytes in the > PHP_MINIT_FUNCTION and I had no problems. > > The situation you described seems as you have called shmctl with IPC_RMID > but not everyone had detached from the segment.
